"The Poor installation rating had nothing to do with K&N but rather with The GM engineers that designed the HHR. The engine cover, Mass sensor, and two air hoses had to be disconnected in order to change the filter. I've used K&N air filters before and have only been pleased. I just installed this on my HHR so its to early to see any mileage gain but the car does seem to respond better when I step onthe accelerator. Overall I'm very pleased with my purchaseof this filter as well as my HHR.Bob" —Robert G from Kingwood, TX bought a K&N Air Filters for a 2008 Ford Focus.
